Description of the Invention (1) Field of the Invention The present invention relates to a power circuit, a machine having the power circuit, and a control method of the power circuit, and particularly to a power circuit suitable for use when the supply is provided to a load. The flow of the load changes periodically. For example, the power supply part of the power amplifier transmits a radio wave, which is embedded in a portable mobile phone 'and an electronic device with the power supply circuit, and the background of the invention of the power supply circuit controller is in use. In the power circuit of a chemical battery, when a load with a negative load is connected, the load current changes periodically. Because of the relatively large impedance of the chemical electricity β, the voltage will drop simultaneously and instantaneously. Time. To solve this question yes. In capacitors, capacitors with lower impedance are connected in parallel to ... Yuhuai is connected to a chemical battery. In this case, the decline rate will be reduced. When the phase and reactance are formed in it, it is the case. Focusing on the same chemical battery, the conventional power circuit, such as 筮 and a capacitor 2, is shown in a parallel diagram, which has a chemical connection to the chemical battery 丨 and electric six w to the chemical battery 1, and a | 'for example a Nickel-cadmium batteries,. The chemical battery 1 is composed of a primary substance, or an alkaline main = hydrogen battery, a lithium ion battery, and generates an electric charge ::, and stores a load L. The chemical battery 1 has a (ie, voltage) VI with __ internal impedance 1 a. Capacitor 2 series of electronics should be used to load the load, for the purpose of the method. When loaded, > Inside, when the instant I, in the learning battery I, the battery 1 used is instantaneously lower than the battery L or a similar fixed amount to be supplied to the club. 575995 V. Description of the invention ( 2) It is composed of-~ ^ double-layer capacitive states, i and the voltage v of the chemical battery], 'to accumulate electricity' and provide the accumulated electricity to the load L. Capacitance: 2 has-internal impedance 2a. For example, the load 1 is a power amplifier for transmitting-transmitting radio waves, which is embedded in a portable mobile phone. The load current is periodically changed, and a pulse-shaped load current flows therethrough. FIG. 8 is a time t diagram illustrating signals of the operation of the conventional power supply circuit of FIG. 7. FIG. Current and voltage are plotted on the vertical axis, while time is plotted on the horizontal axis. The operation of the power supply circuit in FIG. 7 is shown in FIG. 8. At time u, a load current IL will increase instantaneously, and the voltage VI of the chemical battery j will drop from the voltage value Va to the voltage value Vb. In this case, the internal impedance Z of the power supply circuit is expressed by the following equation: Z = R1 X R2 / (R1 + R2) Equation (1) where " R1 " is the value of the internal impedance la, and "R2" is the value of the internal impedance 2a. Therefore, the internal impedance Z is smaller than the internal impedance 1 & The voltage value "is smaller than the voltage value vc generated when the power source is composed of the chemical battery 1. At time t2, the pulse-shaped load current] ^ will decrease instantaneously, and the voltage vi of the chemical battery 1 will return from the voltage value Vb to the voltage value Va. The voltage νι of the capacitor 2 is changed in the above-mentioned manner. Therefore 'when capacitor 2 is connected to chemical battery 1 in parallel, since the drop rate of voltage value Vb is less than voltage value ^, if chemical battery 1 is composed of a secondary battery, the time used for each single charging cycle will change Compared with the power circuit, it is composed of only one chemical battery. Furthermore, ’Dang Chemical Battery 1 is made of alkaline main battery with high internal resistance.

Description of the invention (3) When completed, the life of the power circuit will be longer, compared to the case where it consists of only one chemical battery 1. However, the conventional power supply has the following problems. That is, whether the remaining capacity of the 'chemical battery 1' in the electronic device is basically sufficient, and the instantaneous decline occurs only based on the decrease in the battery voltage, and the remaining capacity of the chemical battery 1 = is insufficient. However, 'If the chemical battery 1 is composed of batteries, the battery is °° Even if the remaining capacity of the chemical battery 1 can operate an electronic device', the same remaining capacity will be judged to be sufficient to operate another Electronic machine. The capacity has not been completely exhausted. That is ,: learn an electric current cell = judged to be at the end of its life, "the discharge of the Chinese chemical battery!" That is, the ratio of the discharged capacity to the quantitative capacitance) is] 'again (also = the current chemical battery Use the problem of reduced energy efficiency. Again: The dry cell 1 is composed of a secondary battery, such as a nickel-cadmium battery, a lithium-ion battery, or the like.

Description of the invention (9) A second power storage section uses electric power from the power supply section to charge to accumulate power; and a control section for load bursts in odd order during the load burst During the power generation period, the power accumulated in the first power storage section is provided to the load, and the power accumulated in the second power storage section is provided during an even-numbered load burst during the load burst period. In the aforementioned sixth aspect, the preferred mode is related to a portable mobile phone. Another preferred mode is related to a digital still camera. With the above configuration, since the load is driven by the electric power accumulated in the first power storage portion during the load burst of the odd order, the load is accumulated by the load during the load burst of the even order. Driven by the electric power in the second power storage section, even if the load burst period occurs periodically, the power ratio during the load burst period exceeds 50%, and the energy required during the load burst period will come from The first power storage part or the second power storage part, and a chemical battery will not be discharged during the load burst. Therefore, the amount of voltage drop caused by the internal impedance of a power supply portion will become smaller. Therefore, when the above-mentioned power supply circuit is applied to the electronic device, the electronic device will become inoperable due to the temporary voltage drop of the power supply. The operational life of the supply section becomes longer.
